Arbotom®

2D/3D Sonic Tree Tomography

rinnntech arbotom

The Arbotom® is used in advanced tree risk assessments. By evaluating the condition of the wood quality in the entire cross section, strength loss due to decay can be assessed. That data is then used to gain a better sense of what is happening to the tree and how that might affect the likelihood of failure component in a risk assessment.

When conducting advanced tree risk assessment it is often important to know the extent and configuration of internal decay. The Arbotom uses sonic tomography to detect areas of wood in good or bad condition.

A series of sensors are placed around the tree trunk or limb, each one connected to the next and then to a computer. Each sensor is tapped, which sends a stress wave across the wood to the other sensors. When wood quality is high (solid wood no defect) the stress waves travel rapidly. When wood quality is low (decay present) the stress waves take longer to move through the wood, and if wood is missing (cavity, or crack) they have to travel around that area, thus taking a lot longer to reach other sensors. The data produced is called a tomogram, which provides a display of the stress wave travel times. Interpreting the tomogram allows the user to get a better sense of where decay might be present, as well as the type and extent of the decay. Used in conjunction with the strength loss module, users can then better predict what may be happening inside the tree.

In many cases it is useful to use a Resistograph® as a follow up diagnosis by drilling at one or more of  the Arbotom sensor points to confirm the presence or absence of decay and refine the analysis.

When used in combination with the new ArboRadix™  root sensor module, the Arbortom can be used to help locate roots underground.

Sonic tomography is intended for use on standing live trees. It does not work well on timber structures such as totem poles or bridge timbers due to the lack of variability in moisture content, and may give misleading results in green wood that has been felled and is starting to dry out.

Flexible

Use 6 or 8 Sensors for 2D images of small cross-section and up to 24 to create a 3D image of bigger stems.

Fast & Easy to Handle

Setup, measure and evaluate within about 15 minutes.

Non-Destructive

Sensor pins are driven only a few millimeters into the wood.

Precise

Software documents all data, including individual measurements.

All-in-one Kit

Sensors are connected by standard computer cables (1m up to 25m). Cables/Sensors can be exchanged and extended individually. Connection to PC & Windows via cable (serial RS232 or USB) or Bluetooth.

Arbotom sensor

Self-calibrating sensors

Sensors self calibrate. Placement is based on the geometry of the tree. One tap per second, and easy to use software allows for immediate check of data quality.

Arbotom scan profile

Species-specific algorithms

Species-specific algorithms, and optional color schemes allow for detailed analysis of decay data.

Several configurations available to suit your budget and needs. Capabilities can be extended by adding the Mechical Module for strength loss analysis, the Statistics Module for data evaluation and the Arboradix root sensor module.

The Word Resistograph

The U.S. Trademark Trial and Appeal Board (TTAB), in late October 2019, dismissed the petition of IML Instrument Mechanic Labor, Inc. for cancellation of the RESISTOGRAPH® trademark in the USA “with prejudice”. This means that the RESISTOGRAPH® trademark continues to be an exclusive trademark belonging to Frank Rinn, the inventor of the term (“RESISTOGRAPH”) for his inventive high resolution resistance drilling devices. Frank Rinn has been developing these high quality machines in Germany since 1986 and his RESISTOGRAPH® trademark is registered in approximately 40 countries. Only machines made by Rinntech are the original Resistograph® devices and entitled to use the Resistograph® trademark. Only data collected with a machine made by Rinntech provide Resistograph® data.
